Nitrogen release and decomposition by cover crops in organic no-till systems

Cover crops provide environmental and economic benefits to agricultural systems- reducing soil erosion, increasing soil organic matter, managing soil moisture, controlling weeds, increasing biodiversity, cycling nutrients, and increasing water infiltration. Cover crops increase nitrogen availability to cash crops through nutrient scavenging and reducing leaching of nitrate. Leguminous cover crops fix nitrogen, further increasing soil nutrients supplied to cash crops. Providing increased organic matter in low productivity and disturbed soils can result in increased yields.
